REMOVAL

1.

Open the driver and front passenger window, and then disconnect the battery cable from the negative ter-
minal.

CAUTION:

Before disconnecting the battery, lower both the driver and passenger windows. This will prevent
any interference between the window edge and the vehicle when the door is opened/closed. Dur-
ing normal operation, the window slightly raises and lowers automatically to prevent any window
to vehicle interference. The automatic window function will not work with the battery discon-
nected.

2.

Remove front air spoiler (with front air spoiler).

3.

Remove engine front undercover, using power tools.

4.

Remove engine right side undercover.
